“I studied the Koran a great deal. I came away from that study with the conviction there have been few religions in the world as deadly to men as that of Muhammad. So far as I can see, it is the principal cause of the decadence so visible today in the Muslim world and, though less absurd than the polytheism of old, its social and political tendencies are in my opinion to be feared, and I therefore regard it as a form of decadence rather than a form of progress in relation to paganism itself.”

Letter from Belfast ( 5 August 1953) http://fridaynightboys300.blogspot.com/2010/10/many-letters-of-philip-larkin.html to Monica Jones
Context: You know I don’t care at all for politics, intelligently. I found that at school when we argued all we did was repeat the stuff we had, respectively, learnt from the Worker, the Herald, Peace News, the Right Book Club (that was me, incidentally: I knew these dictators, Marching Spain, I can remember them now) and as they all contradicted each other all we did was get annoyed. I came to the conclusion that an enormous amount of research was needed to form an opinion on anything, & therefore I abandoned politics altogether as a topic of conversation. It’s true that the writers I grew up to admire were either non-political or Left-wing, & that I couldn’t find any Right-wing writer worthy of respect, but of course most of the ones I admired were awful fools or somewhat fakey, so I don’t know if my prejudice for the Left takes its origin there or not. But if you annoy me by speaking your mind in the other interest, it’s not because I feel sacred things are being mocked but because I can’t reply, not (as usual) knowing enough. … By the way, of course I’m terribly conventional, by necessity! Anyone afraid to say boo to a goose is conventional.

1920s, An Autobiography (1927)
Context: I am a Hindu by birth. And yet I do not know much of Hinduism, and I know less of other religions. In fact I do not know where I am, and what is and what should be my belief. I intend to make a careful study of my own religion and, as far as I can, of other religions as well.

"The Emotional Factor"Religion is based, I think, primarily and mainly upon fear.
Often paraphrased as "The Christian religion has been and still is the principal enemy of moral progress in the world."
1920s, Why I Am Not a Christian (1927)
Context: You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.
